To all whom it may concern:

Be it known that l, ALBERT R. WEIsz, a citizen of the United States, residing at the city of New York, borough of Brooklyn, county of Kings, State of New York, have invented certain new and useful Improvements in Automatic Turning shapin and Finishing Machines, of which the ollowing is a specification.

This invention relates to improvements in automatic turning, shaping, and finishing machines; and the object of my invention is to provide a new and improved machine of this kind which is simple in construction, rapid and entirely automatic in operation, and is to be used for turning, shaping, and finishing small objects-such as bindingposts, .bored nipples, and similar articlessuch as are usually made on monitor lathes.

In the accompanying drawin s, in which like letters of reierence indicate ike parts in all the figures, Figure 1 is a plan view 01 my improved automatic turning, shaping, and finishing machine, parts being brokenaway. Fig. 2 is an elevation, parts being broken away. Figs. 3 and 4 are vertical sectional views on the lines 3 3 and 4 4 of Fig. 1, respectively. Fig. 5 is an enlarged detail longitudinal sectional view of the automatic chuck. Fig. 6 is a front end View of the same. Fig. 7 is a rear perspective view of a part of the same. j

The entire mechanism is mounted on a bed-plate A, having suitable uprights A, in

which the main shaft B is mounted to turn,

said shaft carrying a belt-pulley B at one end. Near one end of this shaft is mounted a cam-wheel 0, provided on its with a lateral cam projection G, which, as shown, gradually extends from the side of the wheel and then from its highest point approaches the side of the wheel suddenly. j This cam G acts on a roller C mounted on one end of a lever C pivoted at G to swing horizontally. The short end of this lever C bears against the end of a non-rotativ'e spindle D, guided to move len thwiseand horizontall in-standards D on t e base-plate A, and tliis spindle D between the two standards D is surrounded by a spring D which presses the spindle against the end of the lever C A suitable drill or boring-tool D is mounted in the opnosite end of the spindle D. It is clear that when the cam-disk C rotates and acts on the lever C it will cause the spindle D and its drill or boring-tool to be gradually moved in the direction toward the right, Fig. 1, and after the roller G has reached the highest point of the cam projection C the spindle and the boring-tool will be rapidly withdrawn toward the left under the action of the spring D A carriage E .is suitably mounted and guided on the base-plate A to slide transverselythat is, at right angles to the spindle D, for example-and this carriage E is connected by a pivoted link E with a lever E extending upward and mounted to rock on a shaft E held in horizontal arms E pro jecting from the frame of the machine. The link E is provided-with a slot E in which a pivot-pin E projects from the rocking lever E, which pivot-pin is surrounded by a box E mounted adjustably in the slot E and which box can be adjusted .by means of a screw E thus permitting of an adjustment of the effective length of the link E. 'A camdisk F is fixed on the shaft B in such a manner that its rim can adt on a roller E" on the upper end of the rocking lever E and this cam is provided on part of its circumference with two flat portionsff and between them with the raised portion 9. A chain or rope B is attached to the opposite end of the carriage or-slide E and passes over a pulley B and to the lower end of this chain or rope a weight B is attached, which weight thus serves to keep the roller E of the rocking lever E in contact with the rim of the camdisk F. i

The carriage E carries two uprights G G a short distance from each other, both lengthwise and transversely of the entire machine. A suitable stop-plate G is bolted on theupright G and is provided with apro'jection G w ich forms a stop for the material from which the articles are to be made'for examle,.a rod of metal B. This projection is so shaped that the corner g formed by its bottom edge at the inner end is in exact line with the boring-tool D or drill, so that when this boring-tool moves in the direction of its length toward and beyond the stop-plate G the tool will contact with this corner g and thus be guided in its movements, understanding, of course, that atthat time this stop-plate is in 1 article, and its function is merely that of cutof the chuc provided at .its outer ting off. The shaping member h of the tool Gr is of less diameter than the part it, and it is so shaped and formed as-to cut into the roj ecting end ofthe rotating rod of metal, to

such an extent as togive this projection any desired shape. For example, it may cut a series of grooves and ridges, or it ma give any other fanciful shape to the outer ace of the rod. It will be observed that the cutting member h is in front ofthe shaping member 7& The tool G does not rotateand is so held and secured that when. the carriage E is moved transversely to the length of the machine the parting or cutting member it will first out a part off the roj ecting end of a rotating rod fed through t e machine, and thereupon the shapin member it will act on the outer surface of tTiis rotating rod and cut and shape the same in such amanner as may be desiredthat is, according to the formation of the member if of this tool. I have shown four cutting members i on this tool; but it is to be understood that only one or more may be provided, one only, however, being used at the time, and to use another the tool G must be readjusted. v 1

A chuck H is mounted rotativel in two suitable bearings J on the frame 0 the machine and is rovided with a pulley J over which a driving-belt H passes. The pulley J 2 can be adjusted by means of two screws J which conical ends are adapted to pass to the inverted conical holes J 4 in the body J of the chuck. As is shown clearly in Fig. 5, the vertical conical holes J are larger than the ends of the screws J 'that is, the distance between the bottoms of the holes is slightly greater than the distance between the points of the screws. In case of wear or faulty adj ustment one screw is loosened and the other screw tightened, whereby the pulley J is moved slightly lengthwise in one direction or the other on the body of the chuck, and thus can be adjusted most minutely to compensate for an wear or lost motion. The body J is made tubular, as shown, and is provided at one end with a head K, in the outer end of which the flaring mouth K is formed. The chuck proper, K is provided at its inner end with a tubular screw K and is end with a flaring head and this chuck is split lengthwise toward its inner end, so as to give its aws spring tension, and this chuck also has a'c'entral bore tending lengthwise through the bore of the body J of the chuck and throu h a head M screwed on that end of the chuc -body'J o posite the one provided with ahead K. T e tube L is pro'vlded at the end projecting beyond the head M with a recess forirecerving the shorter end M- of each of two lL-shaped levers M pivoted in the head M,.and these levers M are provided on the free ends of their. longer arms with the beveled heads M. As shown, the head M is rovided with longitudinal grooves M in wffich the longer arms of the L-shaped levers M jcan swing toward and from the body of the chuck.

A sleeve N, having a circumferential groove N, is mounted loosely on the body of the chuck adjacent to the inner end'of the hea M and can be moved lengthwise ofthis body. The sleeve N is provided on the. face adjacent to the head Mwith an annular recess having the beveledsides N at the inner end of which the straight portion N is formed. A yoke 0 extends. into the groove N and projects u ward from aslide O, guided to move in t e direction of the length of the machine on two. horizontal rods 0 A cam-pulley P, fixed on the shaft B, is ro-- vided with a cam-pulley P, in which-a ro lerpin is located, which roller-pin is mounted on the outer end of a lever P pivoted to. swing horizontally, the op osite arm of said lever" extending into the s ide 0, so that as the camulley P rotates with the shaft B the lever% is rocked, and thus the sleeve N moved toward and from the head M on the chuck-body J. Between the rods 0- a pulley Q is mounted, over which a rope or chain Q passes, which has one end attached to a slide Q mounted on the rods 0 and at its,

opposite end carries a suitable weight, (not shown,) so that by the action of this weight the slide Q the chuck-body J. The rod R, from which the articles are to be made, is inserted lengthwise through the chuck-body and the slide Q is pulled back until it bears against the outer end of this rod. Under the action of the weight the slide Q pushes the rod R lengthwise until it rests against the stop G on the carriage E, assumin that the chuck is open. When the sleeve is moved to the left, Fig. 5, and disengaged from the levers M, the chuckiis o on and the rod R can be moved lengtwisei eel When the sleeve N, Fig. 5, is moved to tiie right, the bevel N acting on the heads M of the levers M pressesthese heads toward the longitudinal axis of the chuck-body, whereby the shorter rear ends of these levers M are moved toward the right, Fig. 5, and pull thetube L and is moved toward the head M of chuck K in the same direction. The flaring the combined jaws of the chuck together and firmly against the rod R, which is thus held securely and remains so held until the ring N is again moved away from the head M on the chuck-body. Attention should be called to the fact that when the chuck is openth'at is, when the ring N is moved away from the head M and the chuck-body'is rotatedthe L-shaped levers M have a tendency to swin outward under the action of centrifugal orce, and thus assist in moving the tube L and chuck K lengthwise toward the front end of the chuck-bod so as to assist in opening the chuck, an likewise when the chuck is open the centrifugal force throws out chips that may have passed into the slots in the chuck, and thus keeps the chuck clean. When the chuck is closed, the entire pressure exerted for keeping it closed is taken up by the sides of the flaring mouth K of the chuck-body and need not be taken up by pivot-pins or other parts, thus making the chuck extremely strong, simple, and durable.

The operation of the machine is as follows: When the chuck is open, the rod R is fed forward lengthwise until its front end rests against the stop G whereupon the, chuck is closed by the action of the cam-wheel P on the lever P and the action of the latter by means of the mechanism described on the sleeve N. As soon as the chuck is closed, the cam-wheel G acts on the lever C causing the boring-tool D to be gradually forced lengthwise into the free end of the rod R, resting against the stop G and after the hole has been bored to the desired depth the boringtool is automatically withdrawn, as has a ready been explained. By that time the cam-disk F acts in such a manner as to move the carriage E transversely to the length of the machine or, as illustrated in Fig. 1, from top to bottom. Thereby the stop-plate G is moved out of the line of the axis of the boring-tool and of the rod R, and at the same time the parting or cutting member h of the combined parting and shaping tool G is brought in contact with the surface of the rod and gradually moved across the rod so as to sever a length of the rod equal to the distance between the adjacent planes of the cut-' ting member h and the stop-plate G The 5 5 cam F continues to move the carriage Ein this direction until the sha ing member h of has acted on t e circumferential surface of part of the projecting end of the rod R so as to shape this projecting partaccording to .the

configuration-of the member h. Thereupon parting an shaping tool G the weight B moves the slide E in the reverse direction, so as to remove the shaping member h and the cutting or parting member h away from and out of the path of the rod R, at the same time bringing the stop G into the path of the rod R, and when this stop-plate has arrived in its proper position the cam-pulley P causes the opening of the chuck, permittin the rod R to be fed forward until it stri es the stop G whereupon the chuck is again automatically closed, the rod bored lengthwise, and then that part of the end of the rod which has been previously shaped on its circumferential surface by the member h of the tool G is cut off by the member h of the tool .G", and the circumferential surface of the now new end part of the rod is shaped as previously described. The tool G is withdrawn, the stop brought in place, the chuck opened, the rod fed forward and then gripped, and so on.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is' p 1. In an automatic turning-machine, the combination with a rotative chuck and means for automatically openin and closing the same, of anon-rotative dril in line with said chuck, a carriage mounted to move transversely to the axis of the chuck and drill, a stop fixed on said carriage and havinga recess in line with the axis of the drill, a combined parting and shaping tool on said carriage located some distance from the stop in the direction of the movement of the carriage, the stop being also located a greater distance from the chuck than is the combined parting and shaping tool, substantially as set forth.

2. In an,automatic turning-machine, the

combination with a tubular rotative clutchbody, of a longitudinally-movable clutch therein, a belt-pulley surrounding the clutchbody, two screws in said pulley at opposite ends thereof, the inner ends of which screws are made conical, the clutch-body having two inverted conical holes for receiving the conical ends of said screws, the distance between the points of the screws being less than the distance between the lowest parts of the inverted. conical holes in the clutch-body, substantially as set forth.

Intestimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, this 10th day of July, 1905.
